CVE-2026-114441 in php-travel-agency-system
Summary
by MITRE • 10/22/2026
A weakness has been identified in oretnom23 php-travel-agency-system. This issue affects some unknown processing of the file admin/update.php. This manipulation of the argument action/full_name/visa_no/hiden/title/description/page_id/user causes sql injection. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.

Analysis
by VulDB Data Team • 10/22/2026
The oretnom23 php-travel-agency-system contains a critical SQL injection vulnerability within its administrative interface, specifically located in the admin/update.php script. This flaw stems from improper validation and sanitization of user-supplied input passed through multiple query parameters including action, full_name, visa_no, hiden, title, description, page_id, and user. Because these arguments are processed without adequate protection against malicious SQL syntax, an attacker can inject arbitrary commands into the backend database queries. This type of weakness is classified under CWE-89 as Improper Neutralization of Special Elements used in an SQL Command, which represents one of the most prevalent and dangerous web application vulnerabilities due to its potential for severe data compromise.
The operational impact of this vulnerability is significant given that it resides within an administrative endpoint. Although the specific processing logic affected by each parameter remains partially undocumented, the presence of fields such as visa_no and full_name suggests that sensitive personal identifiable information or travel records are being manipulated. An attacker who successfully exploits this SQL injection can bypass authentication mechanisms, extract confidential data from the database including user credentials and customer details, modify existing records to alter business operations, or potentially execute administrative commands on the underlying server depending on the database configuration and privileges granted to the web application account. The fact that an exploit has already been made public increases the risk of automated attacks targeting this system in the wild.
From a threat intelligence perspective, this vulnerability aligns with several techniques outlined in the MITRE ATT&CK framework for enterprise environments. Specifically, it facilitates Data Injection which is often used as a precursor to Data Exfiltration or Defense Evasion by altering logs and records. The ability to initiate attacks remotely means that no prior access to the system is required beyond network connectivity to the web server, making this a high-severity issue for any organization deploying this software in production environments without additional protective controls such as Web Application Firewalls configured with specific rulesets for SQL injection patterns.
Mitigation strategies must address both immediate remediation and long-term security posture improvements. The primary solution is for developers to refactor the admin/update.php script to use parameterized queries or prepared statements, ensuring that all user inputs are treated strictly as data rather than executable code. Input validation should be implemented at multiple layers, including client-side checks for usability and server-side strict type checking and whitelisting of expected values for parameters like page_id and action. Additionally, since the project utilizes a rolling release model where specific version numbers are not available, administrators must monitor official channels for patches or consider isolating the administrative interface behind stronger authentication controls such as multi-factor authentication and IP allowlisting to reduce the attack surface while awaiting upstream fixes.
